11 Claims. (Cl. 209-215) The invention relates to an apparatus for re- .covering black or other'magnetic sands or silt from streams and the present application is filed to take the place of an abandoned application Serial No. 678,712, filed July 1, 1933, by me for the same subject matter; as that of the present application.

The object of the present invention is to provide a Simple, practical and efficient apparatus of strong, durable and comparatively inexpensive construction, designed to be arranged upon the bed of a stream and to extend from the bottom of the stream either to the surface of thewater or any distance above or below the surface so as to lie in the path of sand or silt traveling in traction, that is, sliding on the bottom of the stream and also sand or silt flowing in suspension and adapted to intercept and attract and collect such magnetic sands and silt, and capable of being readily hoisted from the bed of a stream and moved to a position over a container and of discharging the collected sand or silt and depositing the same within a suitable container,

A further object of the invention is to provide an apparatus of this character equipped with electro-magnets adapted to be energized by a generator either on the bank of a stream or on a barge or the like, and capable of enabling the electro-magnet to be readily energized and deenergized for attractingand collecting the magnetic values in the stream, and of quickly depositing such values when the apparatus has been moved over a container or receptacle for the magnetic sand or silt.

It is also an object of .the invention to equip the apparatus witha grizzly adapted to form a combined guard and deflector in addition to permitting the sand and silt to pass through it to the magnets so that the sand and silt will be operated on by the apparatus and rocks and floating debris, such as logs, will be deflected and caused to pass to'either' side of the apparatus and thereby prevented frompassing through and lodging in the apparatus.

With the above and other objects in View, the invention consists in the construction and novel combination and arrangement of parts hereinafter, fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction, within the scope of the claims, 'may be resorted to without departing .from the spirit or sacrificing any of the advantages of the invention-.; 1 r

In the accompanying drawings in which is i1- lustrated the preferred embodiment of the invention, the apparatus for the recovery of black or other magnetic sand or silt from streams comprises in its construction aplurality of spaced horizontal magnet. supporting members I, preferably arranged in a rectangular group and composed of spaced 'vertical'tiers a'ndformed by hor- 1 izontal sets which are detachably and removably vsupported by transverse rods 2. The magnet sup porting members which may be of any desired number, preferably consist of wooden poles or tubes which preferably extend longitudinally of the apparatus, and the transverse rods which are horizontally disposed, pass through the .endportions of the magnet supporting members and through vertical standards 3 arranged in pairs at the front and rear of thepapparatus and located at opposite sides thereof, as clearly shown in Fig.

Any number of the standards and sets of transverse rods may, of course, be employed, and the transverse rods are detachably secured to the standards by any suitable means to enable them to be removed for detaching any'of the magnet supporting members for the repair of eleCtro-magnets 4 and'5, or

other'purpose. g

The standards 3 which are vertical, are preferably provided at their upper ends with suitable -eyes,6 which receivetransverse rods and spacingl'tubes 8 which space'the lowerends of chains ,or boom ID, a cable II and the said chains!) which are connected at their upper ends to the lower end of the cable and extend downwardly,

and outwardly in a diagonal direction and at an inclination to the upper ends of the standards 3.

The rods 1 pass through suitable end links of the chains and the spacing tubes'or sleeves 8 maintain the ends of, the chains in proper position at A the sides of the apparatus at the front and back thereof. The apparatus is designed to be arranged at and rest upon the bottom or bed of the stream and the hoisting mechanism will enable the apparatus to be readily deposited in the stream upon the bed thereof, and will also enable the same to be easily and quickly removed therefrom for discharging and depositing in a suitable container an accumulation of magnetic sand or silt collected and recovered by the apparatus.

The electro-magnets may be of any desired form or construction, either horseshoe magnets or straight bar or core magnets. The electromagnets 4 are mounted upon the front ends of the supporting members I which are bored at intervals between their ends to provide openings l2 for the reception of the intermediate magnets 5. The openings l2 are arranged both vertically and horizontally to dispose the magnets alternately in a horizontal and vertical position, but they may be arranged in any other position. and may, if desired, extend from two opposite faces of the supporting member or from only one side or face thereof.

The electro-magnets are designed to be supplied with current from a generator l3 which may be operated by a gasoline engine, or any other suitable power, and which may be located either on the bank of a stream or on a barge, float or the like. A suitable switch M is provided for enabling the current to be turned on or cut off for energizing and de-energizing the magnets to enable the apparatus to collect a load of the magnetic material moving along the bottom of the stream or floatingin suspension in the stream and to quickly release and discharge the accumulated material when the apparatus is lifted from the stream and moved over a suitable container.

The apparatus is provided at its front with an approximately V-shaped grizzly I5 forming a combined guard and deflector and composed of two sides arranged at an angle and connected together at the front ends and at their rear ends with the adjacent standards 3 or other portion of the apparatus. The grizzly which is preferably constructed of steel, is provided at each side with a grating which may be formed by spaced parallel strips 16 extending over an opening I1, as clearly illustrated in Fig. 1 of the drawings, but the grating may be of any desired construction, and the slits or openings in the grating are preferably horizontal, asshown and are of suflicient size to permit sand and silt to readily pass through the grizzly so as to be operated on by the magnets of the apparatus and the said openings or slits in the grizzly are sufficiently narrow to prevent any rock or floating debris from passing through the grizzly and lodging in the machine.

The grizzly or any of the parts thereof may be magnetized and be in the form of either permanent or electro-magnets. The apparatus may be made of any desired size and may extend either from the bottom of the stream to the surface thereof, or to a point above the surface, or it may terminate at a point below the surface. It may be left unattended at intervals for continuous operation and after it has accumulated a sufficient quantity of magnetic sand or silt, it may be readily lifted from the bottom of a stream and moved to a position above a container for the reception of the recovered values. The accumulated magnetic sand and silt may be quickly and thoroughly discharged from the apparatus and deposited in the receptacle by simply operating a switch and cutting off the current to the magnets and thereby de-energizing the same. After a load or accumulation has been deposited in the container the switch is operated to reenergize the magnets and the apparatus is returned to the bottom of the stream for repeating the operation. The magnet supporting members, the means for securing and connecting the same and the grizzly constitutes the frame of the apparatus and the weight of the apparatus is ample for maintaining it in proper position on the bed of the stream. The wiring of the electromagnets and the feed wires for supplying the electro-magnets with current may be insulated in any desired manner and may be of any preferred arrangement, the chains 9, the cable II and the boom or beam [0 forming ample supports for the feed wires.
